DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

The following disclosure addresses a need for an improved beverage container sleeve that actively cools and/or heats the contents of a beverage container while helping to maintain the temperature of the beverage once it is cooled or heated. Disclosed herein are embodiments of an improved cooling and/or heating system for a beverage container, a method of manufacturing the container sleeve, and a method of using the container sleeve. The improved beverage container sleeve is configured to cover a beverage container and can actively cool and/or heat the container while helping to maintain the temperature of a chilled or heated beverage after the beverage is cooled or heated by the sleeve.

The improved beverage container sleeve 10 can include a cover 12 and a cooling device 50. As illustrated in FIG. 1, the cover 12 can have a round tubular shape with a closed end 14 and an open end 16. The inner portion of the cover 12 can have a cavity 18 that is open at the upper portion, such that the top of the cover 12 has an annular shape. The cover 12 can form an outer surface 20 and the cavity 18 can form an inner surface 22, as illustrated in FIG. 1. In alternative embodiments, the cover 12 can be open at both ends and have an annular shape at the top and bottom of the cover 12. In these embodiments, the cover 12 can have a through hole where the beverage container can be inserted.

In some embodiments, the cover 12 can include other shapes. For example, the cross sectional shape of the outer surface 20 can be oval, square or polygonal. The inner surface 22 can also include various shapes. Preferably, the inner surface 22 is cylindrical to accommodate most beverage containers. In some embodiments, the cross sectional shape of the inner surface 22 can be other shapes, such as oval, square or polygonal.

The cover 12 is preferably constructed of an insulating material. The insulating material can help to maintain the temperature of the beverage in the beverage container placed within the sleeve 10. The insulating material is preferably elastomeric such that the cavity 18 can expand and enlarge to accept various beverage containers. Furthermore, the insulating material can provide an insulation layer that provides the user with a contact surface that does not transfer heat to the beverage and is not too cold to the touch. In other embodiments, the cover 12 is constructed of other materials such as rubber, foam, plastics or metals.

In some embodiments, the cover 12 can be approximately 4 inches in height and the diameter of the outer surface 20 can be approximately 3¼ inches. The diameter of the inner surface 22 can be approximately 2½ inches. In some embodiments, the height of the cover 12 can range from approximately 2 inches to approximately 8 inches. In some embodiments, the diameter of the outer surface 20 can range from approximately 2 inches to approximately 5 inches. In some embodiments, the diameter of the inner surface 22 can range from approximately 1 inch to approximately 4 inches. In some embodiments, the height of the cover 12, diameter of the inner surface 22 and diameter of the outer surface 20 can be less than or greater than the dimensions disclosed above.

As illustrated in FIGS. 1 and 2, the cover 12 can have cutouts 52 positioned on the inner surface 22 for receiving cooling devices 50. In some embodiments, the cover 12 can have three cutouts 52 for receiving the cooling devices 50. Other embodiments can have more or less than three cutouts 52. The embodiment illustrated in FIG. 2 shows four cutouts 52 to accept four cooling devices 50. Preferably, the cutouts 52 are equally spaced apart from each other for best cooling.

The cooling devices 50 can include gel packs or ice packs. They can be placed in and chilled by a refrigerator or freezer. Other cooling means may also be used. In some embodiments, the cooling device 50 can be affixed to the cover 12 with non-releasable methods, such as adhesives or molding. In these embodiments, the cover 12 with the attached cooling device 50 can be placed in a refrigerator or freezer for cooling. In other embodiments, the cooling device 50 can be removable and can be cooled separately from the insulating cover 12. For example, the cooling device 50 and/or cover 12 can include releasable attachment means, such as reusable adhesives, to mount the cooling devices 50 to the cover 12. In other embodiments, the cutouts 52 can be dimensioned smaller than the cooling device 50 so that the cooling devices 50 can be held in the cutouts 52 by compression forces of the cover 12 on the mounted cooling devices 50. Thus, as mentioned previously, it can be advantageous for the cover 12 to be made of an elastomeric material that can help secure the cooling devices 50 to the cover 12 through elastic compression.

In some embodiments, the cooling devices 50 can be at least approximately one inch in height and at least approximately one inch in width. In some embodiments, the thickness of the cooling devices 50 is at least approximately ⅛ inch. In some embodiments, the dimensions of the cooling device 50 are configured to fit within the cover 12, as disclosed herein.

FIG. 3 illustrates cooling devices 50 positioned toward the middle height of the inner surface 22 of the cover 12. In other embodiments, the cooling device 50 may be positioned in other parts of the cover 12, such as toward the closed end 14 so that the cooling devices 50 can provide cooling even when the beverage container is almost empty. In some embodiments, the cooling devices 50 may be larger and cover 12 substantially the entire height of the inner surface 22 of the cover 12. In some embodiments, the entire inner surface 22 can be covered by the cooling devices 50.

In some embodiments, the cooling device 50 is mounted along the inner surface 22 of the cover 12 so that it can come into direct contact with the beverage container for optimum cooling and efficient transfer of heat away from the container. Mounting the cooling device 50 on the inner surface 22 can also beneficially provide a layer of insulation so that the beverage container sleeve 10 is not cold to the touch, as described above. In some embodiments, there can be a layer of material between the cooling device 50 and the container, such as when the cooling device 50 is inserted into a pocket or when a net is provided to secure the cooling device 50 within the cutout. The layer or layers of material are preferably thin in some embodiments, and can transfer heat away from the container to the cooling devices 50 for efficient cooling.

In some embodiments, the sleeve 10 can be configured to insulate and cool aluminum cans. In other embodiments, the sleeve 10 can also be configured to be used with other containers, such as for example plastic and glass bottles.

Prior to using the beverage container sleeve 10, the user can place the cooling devices 50, or the entire sleeve 10 with the cooling devices 50 mounted, into a refrigerator, freezer or other cooling means. In use, the user can remove the chilled cooling devices 50 from the cooling means and mount them (if not already mounted) to the cavities of the cover 12.

A beverage container can be placed in the cavity 18 of the cover 12 so that the container comes into contact with the cooling device 50. In preferred embodiments, the circumference of the cavity 18 is smaller than the circumference of the beverage container, so that when the container is placed in the cavity 18, a compression force holds the sleeve 10 against the container and also pushes the cooling device 50 against the container for efficient cooling. The cooling device 50 can help cool the content of the container while the cover 12 insulates the container. Preferably, the height of the beverage container is greater than the height of the sleeve 10 so that the user can drink from the top of the beverage container.

After the beverage is consumed, the user can remove the beverage container from the cavity 18 and place another beverage container in the cavity, if desired. In some embodiments, if additional cooling is desired, the user can remove the cooling devices 50 and exchange them for other chilled cooling devices 50, or place the cooling devices 50 in a cooling means to re-chill the cooling devices 50.

In another embodiment, the beverage container sleeve 110 can include a cover 112 that is formed from one or more pieces of material that is folded and joined along particular edges. A cooling device 150 can be coupled to the cover 112 and secured by a net 154, as illustrated in FIG. 4. The net can be made of the same material as the cover. In an expanded configuration, the container sleeve 110 can have a generally round tubular shape with a closed end 114 and an open end 116. The inner portion of the container sleeve 110 can have a cavity 118 that is open toward the open end 116.
